But as the population grew it became difficult for the people to have distinct domain names. In 1995 a company named Network Solutions was granted the rights to charge people for new domain names. And it was so expensive that the prices started at $100 per two years of registration. 30 percent of this was a fee that went to the National Science Foundation to create an 'Internet Intellectual Infrastructure Fund' which was later reversed in 1997, bringing the charge down to $70 for two years.

In 1956 IBM launched RAMAC, the first computer with something like a hard drive that we use today. Back then Hard Drives meant something that used magnetic disks - a moving head was used to access and write that data. RAMAC stood for Random Access Method of Accounting & Control. The whole cabinet weighed over 1000kg and the 5MP data was spread over 50 huge aluminum disks, coated with magnetic iron oxide. The disks rotated at a speed of 1200rpm and the machines were leased for $3,200 per month back in the day.
